- 每个学生一套数据库，长期保存（data/databases/<用户编号>/库名.db）；学生程序运行时挂进沙箱可读写 - Sim.Data：SqlConnection / SqlCommand / SqlDataReader / SqlDataAdapter / SqlCommandBuilder / SqlParameter； 连接字符串只按库名打开学生自己的库；ScriptDom 解析 T-SQL 后按白名单转写成 SQLite 语句， STRICT 表 + 元数据表还原 SQL Server 的列类型，报错编号和中文信息与 SQL Server 一致； INSERT 不写列名时跳过自增列，日期统一格式（书上 DateTime.ToString() 拼接的日期能正确比较） - 常驻 SQL 服务（Sim.Runner sql-server）：数据库页面的查询、对象资源管理器，评分前按实验 database.sql 建库 - 数据库页面（代替 SSMS）：对象资源管理器、查询窗口、编辑前 200 行、表设计器、恢复实验初始数据 - DataGridView（绑定 DataView/DataTable/DataSet，单元格修改写回 DataTable）、DateTimePicker；设计器工具箱加入 - 评分：每个检查项一份新建的实验库；新增点 / 修改表格单元格、选日期、表格里有 / 没有某行的检查 - 示例：项目 6 任务 2、3；时间格式改成和中文 Windows 一致（9:05:03）；异常堆栈不暴露服务器路径 - 测试：数据库端到端、接口（每人只看到自己的库、恢复实验数据）、评分出错情况、T-SQL 生成 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
